The feasibility of inner-field-of-view EPI based on
2D-selective RF excitations to acquire T2*-weighted
images of the human spinal cord in vivo is demonstrated.
Compared to conventional, slice-selective EPI, the
readout echo train is shortened reducing geometric
distortions and lower sections of the spinal cord can be
covered without the need for excessive FOVs to avoid
aliasing artifacts. Like for conventional EPI,
slice-specific z-shimming can be applied to minimize
signal dropouts related to through-slice dephasing.
Thus, BOLD-based functional imaging may become feasible
throughout the spinal cord.
